The principles of natural climate solutions

Nature Communications, Journal Year: 2024, Volume and Issue: 15(1)

Published: Jan. 23, 2024

Abstract Natural climate solutions can mitigate change in the near-term, during a climate-critical window. Yet, persistent misunderstandings about what constitutes natural solution generate unnecessary confusion and controversy, thereby delaying critical mitigation action. Based on review of scientific literature best practices, we distill five foundational principles (nature-based, sustainable, climate-additional, measurable, equitable) fifteen operational for practical implementation. By adhering to these principles, practitioners activate effective durable solutions, enabling rapid wide-scale adoption necessary meaningfully contribute mitigation.

Carbon removal and climate change mitigation by seaweed farming: A state of knowledge review

The Science of The Total Environment, Journal Year: 2024, Volume and Issue: 918, P. 170525 - 170525

The pressing need to mitigate the effects of climate change is driving development novel approaches for carbon dioxide removal (CDR) from atmosphere, with ocean playing a central role in portfolio solutions. expansion seaweed farming increasingly considered as one potential CDR avenues among government and private sectors. Yet, comprehensive assessments examining whether can lead tangible mitigation remain limited. Here we examine results over 100 publications synthesize evidence regarding capacity farms review different interventions through which an may contribute mitigation. We find that presently, majority fixed by seaweeds stored short-term reservoirs (e.g., products) only minority ends up long-term are likely fit within existing international accounting frameworks marine sediments). Additionally, tiny global area cultivated date (0.06 % estimated wild extent) limits present mid-term future. A first-order estimate using best available data suggests that, at present, even low emissions scenario, any provided globally be offset their (median balance net emitter: -0.11 Tg C yr

Enhancement of Maritime Sector Decarbonization through the Integration of Fishing Vessels into IMO Energy Efficiency Measures

Journal of Marine Science and Engineering, Journal Year: 2024, Volume and Issue: 12(4), P. 663 - 663

Published: April 17, 2024

The escalating impact of anthropogenic activities on global climate patterns necessitates urgent measures to reduce emissions, with the maritime industry playing a pivotal role. This article aims examine adoption International Maritime Organization energy efficiency for often-overlooked fishing vessels and their contribution overall decarbonization efforts. analyzes attained technical indices case study large-scale vessel compares them those two cargo ships where IMO already apply. To support proposal, comprehensive analysis eight large purse seine is also presented. results show that 400 GT above could be subject measures. operational challenges, unique sector, suggest sector-specific considerations may required integrate fleet into existing guidelines. Looking ahead, this explores benefits aligning Regulation (EU) 2023/957 guidelines, as well applying Carbon Intensity Indicator (CII) in assessing environmental operations, emphasizing importance including these current regulatory frameworks promote decarbonization.

Protection of seabed sediments in Canada's marine conservation network for potential climate change mitigation co-benefit

FACETS, Journal Year: 2025, Volume and Issue: 10, P. 1 - 14

Published: Jan. 1, 2025

Marine conserved areas (MCAs) can provide a range of ecological and socio-economic benefits, including climate change mitigation from the protection enhancement natural carbon storage. Canada's MCA network is expanding to encompass 30% its Exclusive Economic Zone by 2030. At present, aims integrate protecting coastal vegetated blue ecosystems (saltmarsh, seagrass, kelp). Here, we argue that incorporating unvegetated seabed sediments could bring similar benefits. Seabed store and/or accumulate high densities organic carbon, due their large spatial extent, contain stores orders magnitude larger than habitats. We estimate currently designated MCAs only 10.8% sediment stocks on continental margin, 13.4% with densities. Proposed would cover an additional 8.8% 6.1% total areas, respectively. identify set high-priority for future research potential protection, ranking importance based stocks, proxies lability, ecological/biological significance. The incorporation into networks support preventing releases stored carbon.

Mangrove ecology guiding the use of mangroves as nature‐based solutions

Journal of Ecology, Journal Year: 2024, Volume and Issue: 112(11), P. 2510 - 2521

Published: Aug. 7, 2024

Abstract Mangroves are implemented as nature‐based solutions (NbS) for coastal protection, climate change mitigation (carbon sequestration) and other services. They play a core role in providing benefits biodiversity, livelihoods human well‐being. Ecological research has informed the use of mangroves NbS, but failure NbS projects often been due to misconceptions about mangrove ecology limited wide range ecological knowledge available. Enhanced spatial temporal variation processes, differentiation among tree species assemblages (including fauna microbial communities) provision ecosystem functions services, will support successful NbS. Knowledge responses interacting pressures uses zone resilient projects. Synthesis . The success can be improved with increased incorporation plants, animals microbes by sharing co‐producing within societies.
